摘要

Electrochemical properties of LiFePO_4/carbon composites with various carbon materials were investigated to achieve high-rate charge and discharge properties. LiFePCVcarbon composites were synthesized by a pyrolysis of a LiFePO_4 precursor solution added with porous graphite or particulate carbon powders. The LiFePO_4/porous-graphite composite had a microstructure in which LiFePO_4 particles existed on carbon surface and within pores. The LiFePO_4/particulate-carbon composite had a microstructure in which each carbon particle was covered with LiFePO_4 fine particles. The LiFePO_4/porous-graphite and the LiFePO_4/particulate-carbon composite electrodes showed high discharge capacities of 69 and 30 mAh g~(-1) at a high current density of 4000 mA g~(-1). The high electronic conductivity in the LiFePCVporous-graphite composite contributed to achieving the large discharge capacity at the high current density.
